What is actually happening with the 16 Billion credential leak?

Security researchers discovered 30 databases containing 16 billion records. This was reported to include credentials from major companies such as:

• Apple
• Google
• Facebook
• GitHub
• Telegram
• Various government services

Despite the alarming headline is has been discovered this is not actually a new breach but instead a collection of older leaks - re-packaged into one massive dataset.

Where Did These Credentials Actually Come From?

The data likely originated from:

• Infostealer malware
• Older breaches repackaged into new databases
• Collections pieced together by various actors

What Are Infostealers and How Do They Work?

Infostealer malware is particularly dangerous. It is designed to actively steal passwords, crypto wallets and other sensitive information from infected systems. In particular they target information such as:

• Login credentials

• Browser cookies

Small businesses are frequent targets due to their valuable data and often weaker security measures.

What is Malware and How Does It Threaten Your Business?

Malware (short for "malicious software") represents any program designed to damage, disrupt, or gain unauthorized access to computer systems. Small businesses are prime targets because attackers assume they have fewer security resources.

These digital threats can enter your business through:

• Email attachments and links
• Compromised websites
• Infected USB drives
• Software downloads from untrusted sources

Once inside, malware can steal data, damage systems, and create backdoors for ongoing attacks. The financial impact is substantial. Here are the common types you should know about:

Type	Primary Function	Business Impact
Ransomware	Encrypts files and demands money	Stops operations, costs you cash
Trojans	Pretends to be safe software	Lets hackers sneak into your system
Keyloggers	Records everything you type	Steals your login info
Spyware	Watches what you do online	Steals private info
Worms	Spreads itself across networks	Slows everything down, infects more machines

Real Risks Despite Old Data

• New Credential stuffing attacks
• New Phishing campaigns
• New Account takeovers
• New Identity theft

Protection Strategy	Why It Works
Multi-factor authentication (MFA)	Puts a second lock on your accounts beyond just a password
Password managers	Lets you make and remember strong, unique passwords
Regular password changes	Makes old leaks less useful to hackers
Monitor for breaches	Tools like DarkSub help alert you when business info is found
